Le développement de polymères biosourcés et d'autres matériaux suit la même tendance et constitue un domaine émergent et important.The chemical industry, which remains largely based on fossil resources, is entering a transition phase towards the use of more sustainable bio-sourced raw materials. Rising prices of fossil raw materials and growing environmental concerns, such as greenhouse gas emissions, are driving academic and industrial research to explore the use of biomass for sustainable production of fuels and chemicals . The development of bio-based polymers and other materials follows the same trend and is an emerging and important area.
Les polyéthers aromatiques, tels que les polyéthersulfones, les polyéthercétones et les polyétherbenzonitriles, sont reconnus comme étant des polymères de haute performance du fait de leurs excellentes stabilités thermiques et propriétés mécaniques. Ces polymères ont pour principale application les membranes de séparation en phase liquide et gazeuse. Les polyéthersulfones disponibles sur le marché sont notamment synthétisés à partir de diols aromatiques tels que le bisphénol A ou le 4,4'-dihydroxyphényle avec la dichlorodiphényle sulfone. Les industriels se sont ainsi intéressés à substituer partiellement les diols aromatiques par un diol provenant de la biomasse tels que l'isosorbideAromatic polyethers, such as polyethersulfones, polyetherketones and polyetherbenzonitriles, are recognized as high-performance polymers due to their excellent thermal stabilities and mechanical properties.

Ainsi, Kricheldorf et al. ont d'abord décrit la préparation et la caractérisation de polyéthersulfones contenant de l'isosorbide à partir d'isosorbide silylé et de difluorodiphénylsulfone (
Belgacem et al. ont ensuite décrit la synthèse de polyéthersulfones contenant un 1,4:3,6-dianhydrohexitol et du bisphénol A, à partir de difluorodiphénylsulfone, d'un 1,4:3,6-dianhydrohexitol et de bisphénol A en tant que monomères mis à réagir ensemble dans le même milieu réactionnel (

Ces caractéristiques sont, par exemple, des masses moléculaires moyennes en nombre (Mn) élevées qui sont nécessaires à l'obtention de propriétés filmogènes. Ces polymères peuvent aussi présenter de manière avantageuse une hydrophilie importante : dans le cas d'une membrane, celle-ci va s'humidifier rapidement, ce qui conduit à une filtration rapide avec des débits et des rendements élevés. Enfin, ces polymères peuvent aussi présenter des propriétés de perméabilité, et notamment de sélectivité vis-à-vis de certains gaz et/ou liquides, qui peuvent s'avérer particulièrement intéressantes, dans des procédés de filtration membranaires.In particular, there is also a need to provide polymers of this type, having characteristics suitable for use in the manufacture of membranes.

Il est du mérite des inventeurs d'avoir mis en évidence que l'incorporation de tetrahydrofurane diméthanol dans la chaîne de polymère permet d'améliorer le caractère hydrophile du polymère de l'invention. Cette hydrophilie importante est une propriété particulièrement intéressante pour la fabrication de membranes de filtration : ladite membrane va s'humidifier rapidement, ce qui conduit à une filtration rapide avec des débits et des rendements élevés. La présence de tetrahydrofurane diméthanol dans le polymère de l'invention permet également d'obtenir de bonnes propriétés de perméabilité.It is to the merit of the inventors to have demonstrated that the incorporation of tetrahydrofuran dimethanol in the polymer chain makes it possible to improve the hydrophilic character of the polymer of the invention.

Ce tableau illustre les caractéristiques de procédé mis en eouvre, et certaines des caractéristiques physico-chimiques des polymères résultant. Il démontre bien la possibilité d'obtenir des polyéthers aromatiques avantageusement à partir d'un composé biosourcé.This table illustrates the characteristics of the process used, and some of the physicochemical characteristics of the resulting polymers. It clearly demonstrates the possibility of obtaining aromatic polyethers advantageously from a biosourced compound.
Une membrane est préparée à partir d'une solution du polymère à 20%m dans la NMP coulée sur une plaque en verre. Le solvant est ensuite évaporé à l'aide du cycle thermique suivant : 50°C pendant 12h, 80°C pendant 1 h, 120°C pendant 1 h, 150°C pendant 1 h et 200°C pendant 2 h. Après la cuisson une membrane est obtenue.A membrane is prepared from a solution of the polymer at 20% m in NMP cast on a glass plate. The solvent is then evaporated using the following thermal cycle: 50°C for 12 h, 80°C for 1 h, 120°C for 1 h, 150°C for 1 h and 200°C for 2 h. After cooking a membrane is obtained.
Des membranes ont été préparées selon le mode opératoire général ci-dessus à partir des polymères 1, 6 et 8 selon l'invention en comparaison avec une membrane préparée à partir d'un polymère commercial.Membranes were prepared according to the general procedure above from polymers 1, 6 and 8 according to the invention in comparison with a membrane prepared from a commercial polymer.
Les caractérisations appliquées aux membranes sont décrites ci-dessous :The characterizations applied to the membranes are described below:
L'angle de contact des membranes préparées à partir des polymères 1 et 8 selon l'invention a été mesuré avec l'eau et le diiodométhane selon le modèle de Owens, Wendt, Rabel et Kaelble.The contact angle of the membranes prepared from polymers 1 and 8 according to the invention was measured with water and diiodomethane according to the model of Owens, Wendt, Rabel and Kaelble.
La mesure de reprise en eau a été réalisée avec un appareil de Sorption Dynamique de Vapeur (DVS Q-5000 SA, TA Instruments) à la pression atmosphérique et à l'isotherme de 21°C avec un cycle sorption/désorption de 0 à 90% d'humidité.The water recovery measurement was carried out with a Dynamic Vapor Sorption device (DVS Q-5000 SA, TA Instruments) at atmospheric pressure and at the isotherm of 21°C with a sorption/desorption cycle from 0 to 90 % humidity.
Les résultats sont présentés dans le tableau 2.
Ces résultats montrent que l'hydrophilie des polymères selon l'invention augmente en fonction du taux d'incorporation du tétrahydrofurane diméthanol. En effet, la mesure d'angle de contact des membranes préparées à partir des polymères 1 et 8 permet d'attester de la mouillabilité des films contenant du THFDM par rapport à la référence de PES. L'augmentation de l'énergie de surface en fonction du taux d'incorporation du tétrahydrofurane diméthanol permet la création d'interactions plus fortes du film de polymère avec la goutte d'eau. Ceci conduit ainsi à une diminution de l'angle de contact de l'eau en fonction du taux d'incorporation du tétrahydrofurane diméthanol. Enfin, et de manière particulièrement avantageuse, les polymères selon l'invention présentent une capacité d'apsorption d'eau bien supérieure à la référence : cette hydrophilie beaucoup plus marquée est particulièrement avantageuse pour une membrane, dont la capacité à s'hydrater rapidement va conditionner son rendement et son efficacité.These results show that the hydrophilicity of the polymers according to the invention increases as a function of the rate of incorporation of tetrahydrofuran dimethanol. Indeed, measuring the contact angle of the membranes prepared from polymers 1 and 8 makes it possible to attest to the wettability of the films containing THFDM compared to the PES reference. Increasing the surface energy as a function of the tetrahydrofuran dimethanol incorporation rate allows the creation of stronger interactions of the polymer film with the water drop. This thus leads to a reduction in the contact angle of the water as a function of the rate of incorporation of tetrahydrofuran dimethanol. Finally, and in a particularly advantageous manner, the polymers according to the invention have a water adsorption capacity much greater than the reference: this much more marked hydrophilicity is particularly advantageous for a membrane, whose capacity to hydrate quickly goes condition its performance and effectiveness.
Les expériences sont réalisées à température ambiante. La manipulation consiste à insérer le film à étudier dans la cellule de perméation. Après une désorption sous vide secondaire de 16 h, l'expérience de perméation consiste à imposer une pression (3 bar) d'un gaz choisi dans le compartiment amont de la cellule et à mesurer la remontée de pression dans le compartiment aval de la cellule. La perméabilité est calculée à partir de la pente de la droite pression en fonction du temps dans le régime stationnaire, corrigée du vide statique si nécessaire. Les propriétés de perméation de gaz des membranes préparées à partir du polymère 6 selon l'invention ont été mesurées. Les résultats sont présentés dans le tableau 3.
Ces résultats montrent que la membrane préparée à partir du polymère 6 contenant seulement 25% en mole de THFDM présente une sélectivité pour le dioxyde de carbone par rapport à l'oxygène (6,29) supérieure à celle de la membrane de référence obtenue avec un PES commercial (2,3).These results show that the membrane prepared from polymer 6 containing only 25 mol% of THFDM has a selectivity for carbon dioxide relative to oxygen (6.29) greater than that of the reference membrane obtained with a Commercial PES (2.3).
